Letters .Patent No. 79,632, dated July 7, 1868.

IMPROVEMENT IN GARPBNTERS GAUGES;

TO ALL WHOM IT MAY CONCERN l Be it known that we, O. BROWN and T. F. BERRY, of Oapron, in the county of Boone, in the State of'Illinois, have invented a useful Improvement in Compound Gauges; and we do'hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of `vreference marked thereon, making a part of this specification, in whichvFigure 1 is an elevation of the gauge in position for use. Figure 2, an elevation of the stem removed from the head. FigureA 3, an elevation of the head and a transverse section of' the stem.

lThe nature of our invention consists in 'the use of a polygonal stem, in one side of which is tted aA mortisegauge, having two metallic slides arranged to be set for gauging any common mortise without moving the head.

In' order to give a correct understanding of our invention, We have marked corresponding parts with similar letters, and will now give a detailed description. A

.B represents the stem of the gauge, having six sides,l and A the head,'arranged to slide on said stem in the usual manner. D shows a metallic slide, tted to work deep enough in the stem B foraneuter slide, C, to work ina doveftail groove 'outside' of it, both parts being arranged to move longitudinally when a :set-screw, J', is loosened. A v

v Bythis meansthe head A need not be moved from its position, shown at. iig. 1, in order that the spursf d l may be set at di'erent distances apart,and also to andfrom said head.

When a greater width of mortise is, to be gauged, the head A. can be moved similar to other gauges. VSlides E Gr-F H arev made to work in dove-tail grooves, and are held in position by thumb-screws I I, Svc. These slides have the common spurs, and also projections, c, for moving the slide backand forth.

Itiwill be seen from this description thatl the ganga-as arranged, canrbeusedinstead of four single gauges and one mortisergange, thus providing at small cost a toolwhieh will occupy little room, and answer all ordinary purposes, such as carpenter, joiner, cabinet-w0rk, Svc.' I i The gauge-can beA made of the same kind'ot` material as now used for a similar purpose.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is The combination of the slides D C, head, A, and stem B, substantially as and for the purpose herein set forth.
